Application Example
XPA U 2004 FX
XPA U 2008 FX
Four (XPA U 2004 FX) or eight (XPA U 2008 FX) 200 watt channels into 8 ohms, 4
ohms, 70V, or 100V — These amplifiers are designed for large, high-powered multizone
integration projects.
Configurable output mode per channel — Allows this single amplifier model to be used
in multizone installations with unique configurations per channel.
Flexible power allocation to match system requirements — 400 total watts is shared
between adjacent odd/even channel pairs to provide the right amount of power where it is
needed.
InstaWake+ exits auto-standby mode in under 5 milliseconds — These models
include an auto-standby feature that automatically places the amplifier into standby after
25 minutes of inactivity, dramatically reducing power consumption. The amplifiers quickly
return to full power status in less than 5 ms upon signal detection, with minimal inrush
current. Auto-standby can be disabled if required.
HPF selectable for 70V and 100V channel modes — Prevents saturation of speaker
transformer cores.
Rack-mountable 1U, full rack width enclosure — With the capability to deliver high
performance in one rack space, the amplifiers reduce rack space requirements for many
installations.
Rear rack mounts included — The included rear rack mounts are easy to install and
provide additional stability.
Front to rear fan-cooled — Includes washable and replaceable foam air filters.
Rotary output mode selection switches — Easily, quickly, and reliably select the required
output mode.
Professional grade signal-to-noise and THD+N performance — The amplifiers deliver
professional grade performance, featuring 100 dB signal-to-noise ratio and THD+N of less
than 0.1%.
Ultra low inrush current at power up - no need for power sequencing — Allows
multiple XPA Ultra FX series amplifiers to be powered on simultaneously without overloading
power circuits.
